This I haven't seen officially but a few A340 crew advised the last flight was on 14 April 2003 from Istanbul via Dubai to Singapore. The A340s are parked at various locations around Changi Airport but none at the passenger terminals.

I understand most will forced to clear their annual leave after the fleet is grounded allowing the Airline time to decide their fate.

Current rumour is most of the A310 crew will go to the A340-500 and surprisingly the A340 crew will be spread over all fleets. This might be due to the timing of the fleet grounding more than anything else.
